locations and drill to size 15/64”. Secure tank with hardware provided.
Fig. 1.
HOSE INSTALLATION Fig. 2 & 3
2. Using the high-pressure plastic hose provided, cut to size to be able to
connect the tank to inlet fitting of the accessory or valve requiring
high-pressure air. Place the brass nut from the tank’s outlet fitting onto
the high-pressure plastic hose. Push the plastic hose fully onto the
outlet fitting; tighten the brass nut onto the outlet fitting. CAUTION: Do
not over tighten the brass nut.
3. The other end of the plastic hose is connected to the accessory or
valve requiring high-pressure air.

4. The compressor’s red wire is connected to a (+) 12-volt power source,
using the fuse provided. IMPORTANT! The fuse must be connected
directly to the power source. IMPORTANT! The red fused wire must
be connected to a (+) 12-volt power source controlled by the vehicle’s
ignition switch. This will protect your compressor from running
continuously and being damaged if an air leak develops when the
vehicle is not in operation. Suggested connection points are: blower
motor, windshield wiper motor or the accessory terminal on the fuse
panel. Make sure the connection point has a wire that is as heavy
as the compressor’s wires and the connection point is capable of
handling 20-amps. CAUTION: remove the fuse from the fuse holder
until installation is complete.
5. OPTIONAL: A switch can be installed into the compressor’s red wire.
This will permit the driver to turn-off the system if it is not required.
See Fig. 4.

6. The black wire is connected to ground; secure the black wire’s looped terminal to either the vehicle’s (-) battery
post or under any metal body bolt. Make sure that the ground connection is free of rust, paint and corrosion.
NOTE: The compressor is now ready to be used. Install the fuse back into the fuse holder and the compressor will
automatically turn on.
When the pressure drops below 80 PSI in the tank, the pressure switch will automatically turn on the compressor. When
the tank pressure is approximately 110 PSI the compressor will automatically turn off. If the compressor does not shut
off after 4 minutes of running time, check all air hose connections for leaks. Use soapy water or bubble solution on each
fitting, while the compressor is pumping. Use a thread sealant if leak persists after tightening.
